If you suddenly ask, what diseases are the most common recently?
I think thyroid nodules should also have a place.
As an endocrine organ of the neck, the thyroid hormones secreted by it have the effect of controlling metabolism and regulating body temperature, which is very important for health, and if the thyroid gland has problems, it will affect the various systems of the body.
However, in recent years, the incidence of thyroid diseases has risen significantly, especially thyroid cancer, which has increased at an average rate of 20% in the past 20 years, which is the fastest growing of all malignant tumors.
Is the high incidence of thyroid nodules related to iodized salt?
As early as 27 years ago, in order to solve the problem of insufficient national iodine intake, China launched the "national iodized salt" activity. With the gradual abundance of food and the high incidence of thyroid nodules, many people have a lot of doubts about iodized salt.
But in fact, the high incidence of thyroid nodules has nothing to do with iodized salt.
According to the data, in areas with iodine adequacy and iodine excess, thyroid nodule detection rates were 21.8% and 20.7%, respectively, and there was not much difference, and it was not found that more iodine supplementation could increase thyroid nodule problems.
The main reason for the high incidence of thyroid nodules is not that Iodine is eaten too much, but with the development of medical technology, the discovery rate of thyroid nodules has gradually increased.
Thyroid cancer, too, can not be ignored
In recent years, the incidence of thyroid cancer has gradually increased, growing at an average rate of about 20% per year, becoming the fastest growing malignancy.
Why is thyroid cancer so high in recent years?
First, the intake of iodine is unreasonable
Excessive or too little intake of iodine can affect thyroid function. The lack of iodine in the body can affect the synthesis of thyroid hormones, causing thyroxine levels to rise, thereby increasing the risk of thyroid cancer.
Excessive iodine intake increases the risk of papillary thyroid cancer. Therefore, the daily diet should control the intake of iodine and stay away from the problem of thyroid cancer.
Second, radiation injuries
The occurrence of thyroid gland is also related to a person's working environment, if you work in an environment containing radiation for a long time, it can cause damage to the body, affect the secretion of thyroxine, and eventually induce cancer.
For the sake of health, it is usually necessary to stay away from those more polluted environments and objects containing radiation, and take protective measures.
Third, genetic factors
It is understood that about 5% to 10% of thyroid cancer in the clinic is related to genetic factors, and people with a family genetic history have a greater chance of developing the disease.
Such people should take precautions every day and regularly go to the hospital for relevant examinations to prevent diseases from causing harm to health.
Fourth, the pressure is too great
Nowadays, people's life pressure is increasing, if the spirit is too nervous, anxiety, can lead to the secretion of thyroid hormones affected, over time, can affect thyroid function, increase the chance of thyroid cancer.
It is recommended that you pay attention to the combination of work and leisure to release pressure and help prevent the occurrence of thyroid diseases.
In addition to the above reasons, the progress of detection methods has also led to a significant increase in the detection rate of thyroid cancer.
Previous detection methods can not detect some tiny tumors, but with the popularity of high-resolution B ultrasound, many small, or even only 1 to 2 mm nodules and tumors can be found.
Thyroid nodules can also worsen into lung cancer
Keep in mind that about 10% of thyroid nodule patients eventually progress to thyroid cancer. So once diagnosed as a thyroid nodule, how exactly can a malignant nodule be treated?
1. Radiotherapy
Radiotherapy can be divided into radionuclides and external beam radiation, which are the most important auxiliary means of thyroid cancer treatment.
Among them, radionuclides can take advantage of the characteristics of cancer cells to absorb iodine, and collect high concentrations of iodine in tumor tissue to kill cancer cells.
External beam radiation alone has no therapeutic benefit and is only suitable for a small proportion of patients.
2. Chemotherapy
Chemotherapy can be used on the basis of radiation therapy or in parallel with radiation therapy.
The choice of chemotherapy regimen is determined by the type and stage of tumor pathology, and platinum, purple shirt and anthracycline are all drugs for chemotherapy for this disease.
These drugs can produce symptoms associated with bone marrow suppression, such as anemia and leukopenia, and require termination of treatment if symptoms are severe.
In addition, because thyroid cancer can be divided into many types, different types of chemotherapy are different. Among the many types, the differentiated type responds poorly to this treatment, so chemotherapy is necessary.
